OK, here are more things that get my goat (and he's really very annoyed now):
1. Post titles that don't tell you what it's about (e.g. "Need help; "Scope for sale", etc.)
2. Ice Trade posts where you can't tell whether the person is 'selling' or 'wanting to buy'.
3. Trades where you only find out the item's been sold when you start reading them.
4. Great astro photos but sometimes woeful photos of equipment, etc. (Hint: To best show off your stuff for sale, don't use direct flash, arrange some sort of diffuse lighting ... outside under cloud is good. There's been rather a lot of 'tent' lighting recently so there's no excuse.)
5. flowof consiousness sort of Stuff that a lacking any punctuation andor b go on for ever and ever with typas all over the plaice and even, wrong apostrophie's and no real structeur or stuff like that know what i mean its possibly forgivable sometimes as the state of educatn of today but usually never justifyable I reckon?
6. Deliberate or sureptitious (sorry, surreptitious) cruelty to goats in any post.
There's more, but I can't think of any at the moment, and anyway, complaining isn't going to get anyone anywhere, so what's the point?
Uh-oh, it's happy hour now, so ...
